NITED STATES BENAIAH TITGOMB, OF BALTIMORE, MARYLAND.

IIVI PROVEMENT IN HRVE-STERS.

Specification forming part of Letters Patent No. 42,416, dated April 19, 1864.

erence marked thereon.

Figure 1, letter A, is a perspective view of the machine; Fig. 2, inside View of frame, friction-roller, and rock-shaft; Fig. 3, letter D, frame and yoke in one continuous piece; Fig. 4, letter B, friction roller; Fig. 5, letter C, rock-shaft.

The nature of my invention consists in the invention of a frame and yoke, Fig. 3, letters D D', in one continuouspiece, which will give great strength te the fratrie and is to be used in raising and lowering the machine While working; also, providing frame D D, Fig. 3, with a friction-roller. The roller is attached to the frame by a piti immediately under the rock-shaft G,-for the purpose ot' preventing friction on thebox of the rock-shaft, as seen in the inside `view, Fig. 2, G D B.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

. First. I construct a main or driving Wheel, A, ot' iron with a double semicircular camg'r'oove sunk iutheinner 'surface or disk.

Second. I construct a friction roller or ball of spherical shape adapted to the shape of the outer groove and operating therein, which by its revolving motion would clear the groove ot' all foreign matter.

Third. I construct a hinge-lever, C, or its equivalent, firmly and substantially o`n the top ofthe rock shaft or crank. On the end of the said rock"sli"'t`t"o`""`l'e'e'r next to the Wheel is placed the ball or roller.

Fourth. I next construct a frame and yoke, Fig. 3, letters D D', in one continuous piece.

Fifth. I construct a friction-roller, B, Fig. 4, which is attached to the frame directly under the rock-shalt C, as seen on the inside view, Fig. 2, G B D.

What I claim as my inventiornand desire to secure by Letters Patent, is as follows:

1. Attaching the friction-roller B, Fig. 4, to the side ofthe frame D, directly under the vibrating arm of rock-shaft (l, Fig. 5, in the manner and for the purpose specitied. u

2. The construction of the frame D and yoke D', in one continuous piece, in the manner and for the purpose substantially as set forth.
